Application filed December Toallwkomz'tmay concern'. Beit known that I,GEORGEVV. 'Winton ,1a-citizen. of. the United States anday resi-,rV dentof Hazleton, in `the county o f Luzerne i and State of Pennsylvania,have invented an Improvement Coall Jigs, .oiwhich the following 1safspec1iication-; .Y

-1 `-My. -invention relates to jigsfor vide an improved means wherebythe separal .tion of the coal'and slatemayV be effected,l moreefficlentlyjand more expeditiously than' heretofore, astar as practical.f

Somewhat more speciically stated my in- Averition comprises:inf-'improvement 1in the= means-for preventing returihor reverse vZ-owofthe water through the openings in.

Having thus described my invention,

what I claim and desire -to secure by Letters Patent is: Y

l. In a coal jig comprising a tank having Water therein, the combinationof a jig pan partially submerged Within said Water, means for causingvibratory and rocking movement ofthe said jig pan, a receptacle ofseparate structure situated underneath the said `jig' pan and detachablycarried thereby,^the upper side of said receptacle being closed by thebottom of the said jig pan, andthe said receptacle being provided withvalve controlled openings in the bottom thereof, substantially asdescribed.

2. In a coal jig comprising a tank having Water therein, the combinationof a jig pan, a pan-like separate structure situated underneath the saidjig pan, means for detachably securing the said pan-like structure tothe said jig pan, the said pan-like structure inclosing a chamberunderneath the bottom of the said jig pan and the bottom of the saidpan-like structure being provided with plurality of openings and valvesfor opening and closing the said openings, the said valves beingactuated by the movements of the said jig pan and pan-like structureWithin the .Water of the said tank. Y

3. In a` jig comprising a tank adapted to contain Water, the combinationof a jig pan,

` means for effecting vibratory and rocking movements of the said pan, apan-like structure underneath'the said jig pan and having upper edgeportions thereof secured to the said jig pan whereby the said pan-likestructure partales of the movements of the said jig pan, and the bottomof the said pan-like structure being provided With a vpluralityoff-.openings therein arranged in rows, and a plurality ofdisconnectedstrips Y independently and movably retainedin position overthe said openings to control the passage of Watertherethrough during thevibratory and oscillatory movements4 of the said jig pan and pan-likestructure.

4i. In a coal jig comprising aftank adapted to contain Water, thecombination of a jig pan, means for effecting vibration thereof, areceptacle situated underneath the said vjig pan and forming a chamberunderneath thel bottom thereof, the bottom of said receptacle beingprovided with. a plurality of valve cont-rolled openings for-controllingthe flow of .Water from 'the tank finto the vsaid chamber ofsaidreceptacle and into the said jig pan, and means for detachablyconnecting the said receptacle to thesaid jig pan.

5. In combination, a jig pan which is adapted to be' vibrated, the saidjig pan having openings throughthe bottom thereof, a pan-likemembersituated underneath the bottom of *the said jig. pan and alsohavingVholes through "its bottom, said pan-like member being pivoted to one endportion of the said jig pan, the otherend of said pan-like member havingdetachable `@conf Vnec'tion with the said jig pan, and valves within thesaid pan-like member for opening and closing the holes through thebottom thereof.

6. Ina coal Y jig comprising a tank having Water therein,

the combination of'a jig pan SOA partially' submerged Within said Water,the o bottom of said jig pan having perforations` extendingtherethrough, a supplemental structure supported upon said jig pan andsituated underneath the same, the said supplemental structure beingprovided with valve controlled openings which are adapted to be openedupon the descending movements of the said jig pan and are adapted toclose upon the ascending `,movements thereof, and means carried'by saidsupple.- mental structure tending to prevent lateral HOW of the Waterfrom underneath the same upon the descending'movements thereof.

In testimony .that I claim Ythe fore as my invention, I have hereuntoslgned my name this 17th day of Dec., A. D.- 1921.,
